1. An exterior mirror for a vehicle comprising a base member having a mounting face adapted to engage the vehicle body, an arm secured to the base member so as to project laterally in the opposite direction to the mounting face, first pivotal engagement means mounted on said arm and defining a pivot axis, a housing for a reflective member, second pivotal engagement means on said housing, a first link pivotally attached at one end to a point on the base member which is nearer to the mounting face than the pivot axis, a second link pivotally attached to the first link at its other end, a projection on the base member located between the pivot axis and the point of connection of the first link to the base member, resilient means for urging the first and second pivotal engagement means into engagement with one another so that the housing is pivotally moveable relative to the base member about the pivot axis, the resilient means extending between an intermediate point on the second link and a point in the interior of the housing which is further from the mounting face than the pivot axis when the housing is in a first position of normal use, the second link having a cam surface on the opposite side of said intermediate point to its point of attachment to the first link, said cam surface being arranged to be urged by the resilient means into engagement with the projection on the base member and being shaped so that said projection engages against an abutment at one end thereof when the links are in a position such that the line of action of the spring pulls the housing towards its position of normal use, and to be engaged in a recess at the other end thereof when the orientation of the links is such that the line of action of the spring pulls the housing towards the mounting face, the projection moving between said abutment and said recess as the housing moves between said first position and a second position.
